IIRC 225psi across the cylinders for compression test.
Not sure about leak down exact values you are looking for exactly - just looking for no leaks in each cylinder. Think each piston needs to be at TDC for testing. Gerry @ PerformanceTek done a leakdown test of my B18C6 before - so he would know better - i just watched pretty cool equipment used.

I know consistency across each cylinder is an indicator for a particular bore being an issue, ideally just wanted to get an idea of normal leakage figures as what may be normal for one model of engine may be a bit on the high side for another if that makes sense.
I'm not carrying out the test myself a friend of mine who's a qualified tech of 15 years is doing it. He just asked I find out expected figures so he has an indication as to whether the results point to all being well or not.
